Cold Eggs à la Nantua

Œufs froids à la Nantua (cold eggs with crayfish) teaches one true lesson before you touch a pan: the tail is the garnish, but the body is the sauce. Twelve crayfish serve twice. Their tails fill and crown the eggs, while the bodies, shells, and coral are pounded with cream into the coulis that gives the dish its depth. Throw away the shells and Nantua disappears.

The original entry assumed a cold-pantry cook, thick mayonnaise and clear jelly already waiting, and a tammy through which someone had time to rub every last spoonful of crayfish. Here six eggs become four and eighteen crayfish become twelve, with every ratio kept. A cloth-lined fine sieve replaces the tammy, a half cup of clear stock set with gelatin replaces the standing pan of jelly, and a spoonful of thick mayonnaise replaces making a brigade batch for two teaspoons. Those preparations were scaffolding. The barrel shape, shell coulis, tail rosette, truffle, aspic glaze, and artichoke base are the dish, so all of them stay. One cook, one stove, one evening.

Cold is the discipline here. Every component must be thoroughly chilled before the mayonnaise binds the tails and before the aspic touches the eggs, or the filling loosens and the glaze slides away. Have everything cold before assembly. That is the step that decides the dish.
